Could Vista Update cause a problem?

My flash ad creations were working great (and may still be), but after I downloaded the "Windows Vista Service Pack 1" update, they areas with the flash movies only show up as white space. I know since I have not changed anything on the web site itself, that its appearance shouldn't have changed.

Can anyone see the movie on the left of my web site? It is supposed to be below the Gander Mountain ad and just above the paragraph that begins with the word Safari.

Thanks Chris. I missed that somehow! I placed the >< where they belong now. :)

There is definitely a problem with my computer, though. Here's the sequence of events:
1. Created flash ad
2. Embedded in web page and uploaded to server and verified it was functioning on web page www.brewersafrica.com
3. Prompted by new software installation that Windows Vista Service Pack 1 update was required before new software could be installed.
4. Downloaded Windows Vista Service Pack 1 update.
5. Flash ad no longer visble on my computer when I navigate to my web site, www.brewersfrica.com, even though NO further changes had been made to that web site.
6. Called daughter in South Carolina who checked out the web site and verifed that the flash ad was alive and well and she could see it just fine.
7. I still can't see it on THIS computer, even with the code change. All I see is the empty space where it belongs. I'm wondering if the Windows update boogered up my Internet Explorer 7. (My daughter uses Firefox.)

Anyway, after I create a flash ad here at home, I have to call someone else and ask them how it looks. Big mystery!

Follow OG's advice about browsers. I bought a new computer 2 weeks ago and thought I might as well get up to date on everything. Installed IE8 Beta. Big mistake. Now I can't uninstall and will have to wait for stable version just as OG advises.
